Characteristics of 317L Stainless Steel Pipe / 317L Stainless Steel Pipe Fittings
317L is a low-carbon stainless steel. It is added with chromium, nickel, and molybdenum, so it has better corrosion resistance than 316L. This steel is resistant to sulfur, acetic acid, citric acid, phosphoric acid, chloride, iodide, and formic acid.
